Be it known that I, HERBERT J. KRATZER, a citizen of the United Statesof America, and a resident of the city of St. Louis and State ofMissouri, have invented certain new and useful Improvements in Road-Bedsfor Railway-Rails, of which the following is a specication.

The primary object of this invention is to provide an improved road bedfor the laying of railwayvrails which in itself will be practicallypermanent, in which provision is made whereby the rails c an be removedwithout destroyingv the road bed.

Another object is to provide an improved manner of securing ralls tothis-improved road bed. v

A further object is to provide an improved road bed which in addition tobeing permanent, improved means are provided whereby, when the rails aremounted in position, the usual truing or leveling of the rails is doneaway with.

A still further object of this invention is to provide an improvedconstruction of road bed in which the rails will be resiliently mountedin the road bed, therebyproviding a noiseless sup orting structure.

Other and flirther objects will appear in the specification and bespecifically. pointed out in the appended claims, reference being had tothe accompanying drawings exemplifying the invention, and in which,

Figure 1 is a fragmentary plan View of a portion of this improved roadbed,`showing the rail portions mounted thereon.

Fig. 2 is an enlarged transverse section of eferring to the drawings, 1designates a road bed, preferably constructed of concrete, 1 or the samecan be made of any self harden`v ing lastic material, said road bedbeing rem orced by the bars 2 and 3.

Formed in said road bed -are a pair of longitudinally arranged grooves4, each of said grooves having expanded side walls 5 formed adjacent thebottom thereof, and outwardly Baring walls 6 formedadjacent the topthereof, the bottom 7 of each of said grooves 4 land said expanded sidewalls,4 5 being lmed by a metallic channel member 8.

In the\construction of` this improved road bed, it is g'eferable tofirst elevate the channel mem rs 8 to the desired level, said channelmembers being several feet. in length. Forms are then mounted on each ofthe channel members relative to the making 4 of the upper portion ofeach groove. The

body of concrete is then mounted under and around each of the channelmembers and around the forms, said body of concrete be- 4 ing reinforcedin any desired manner.

When the forms, not shown, `are removed,

a pair of grooves as described is the result, f

the channel members 8 being leftA embedded in the body of concrete. The

l grooves 4 are then ready for the reception of the rails and theirsupporting structure, in which wooden blocks 9, 4which are theapproximate length of the width of the channel members 8, are rst laidin an abutting relation in each vof said channel members, said blocksbeing first treated with a preservative, such as creosote oil. Tar oilis then poured on the blocks 9 to serve as a filling around and betweenthe blocks and also as a further'- preventive- These blocks 9 areagainst deterioration. of a thickness so that the upper surfacesadjacent the ends thereof will engageagainst the inwardly extendingflanges 10 =of the channel members 8. RailsA 11 are then mounted in eachgroove 4 on the laid blocks 9, said rails being gaged relative toyproper wheel tread, and the rail securing lag screws 12 are engagedinto the blocks 9 thereby holding the rails in proper position. Abody ofsand 13 is then laid over each base of each rail-l and on top of theblocks 9. Filling bricks such as 14 and 15 having inclined surfaces 17and 18, respectively, are then mounted in place against the rails and ontop of the body ofsand, the inclined faces of said bricks bearingagainst the outwardly surface 16, such as asphaltum is' then mountved onthe concrete body between the inner rows of bricks 14, and wearingsurfaces such ,as 19 are lled in against`the outside rows of brick.15.This completes theconstru'c-` will serve as deadenersto the sound onac-Q count of the fact that 'the jarring of the f rolling' stock whenapplied to the rails will be transferred to the wooden blocks, and sincesaid blocks are resilient, said blocks will serve somewhat as shockabsorbers to 4 the jarring strains. v

Owing to the fact that it is found that o1l will commence `deteriorationof concrete, attention is called to the channel members 8 which willcontainl the tar oil relative to the blocks 9, which will prevent theoil from coming in contact with the concrete road bed.

The body of sand 13 which is'illed in over the blocks 9 after the railshave been mounted thereon will serve as an insulation to said blocks 9against water seeping into the channel members Sand around the blocks,thereby preventing dampness and subsequent deterioration to the blocks.The

30 bricks 141:v and 15 will also assist preventing water from getting tothe blocks 9, although said bricks are primarily intended to serve asgood wearing surfaces adjacent the rails,

and also to protect the upper edges of the walls of the grooves 4.

Attention is also called to the inwardly extendin bers 8 W ich willserve as a reinforcement to the concrete walls of the groove against 40downward strains, and at the same time serving as a reinforcementagainst upward strains duringl the undulating movements of the railsrelative to the resiliency of the blocks 9 while rolling stock ispassing over It is known that the life of street railway rails is veryshort on account of the traflic thereover being heavy, and in thepresent day methods of removing worn out rails,

the whole roadbed is broken up. It is therefore the intent of thisinvention to provide a permanent road bed with pairs offrail seatinggrooves, in which the filling in or supporting elements or membersrelative to the rails can be easily removed without destroying any partof theroad bed, as all of theparts which are mounted in the grooves 4 ofthis improved road bed can easily be demounted and removed.`

Furthermore the manner in which the rails are .secured in the groovesprovides means for the better securing of the rails to the road bed thanheretofore, as the rails anges 10 of the channel mem- Leonesa arepractically keyed or locked tothe road n bed on account of theengagement of the wooden blocks 9 under the extending vianges 10 of thechannel members'S. v After'the removal of worn out rails from animproved road bed of this character, the grooves 4 are found to bein theoriginal condition in which they were made, and all that is necessaryisa repetition of the mounting of the building or filling structure asafore related, and the rails will be found to have the desired elevationwithout any additional adjustment or leveling of the wooden blocks 9.

What claim is:
